Pyongyang, November 7 (KCNA) -- The Anhak Royal Palace was built by Koguryo Kingdom (277 B.C.-668 A.D.) when it moved its capital to Pyongyang from Kuknaesong (Ji'an in China) in 427. The palace was used by successive kings for about 160 years.

The palace was surrounded by a wall erected with a mixture of stones and earth.

It was 2 488 meters in circumference, each side extending 622 meters, and covered some 380 000 square meters.

The southwestern and eastern parts of the ruined palace are geographically lower than its central and northern parts. By taking the advantage of these conditions, palace buildings were built in a harmonious way.

The palace had 52 buildings in an orderly way in five blocks connected with each other by corridors within the wall.

There were also big and small gardens and ponds and stone-paved roads.

A full-scale unearthing of the ruined palace was made successfully thanks to the Workers' Party of Korea's policy of preserving historical remains and relics.

Discovered at the site were traces of 2 590 columns, tiles, glass-made ornaments, inkstones, arrowheads, nails and earthenware, more than 15 000 pieces in all.

The discoveries offer a glimpse of Koguryo's developed culture.

The ruined Anhak Royal Palace is in Taesong District, Pyongyang.
